Application filed July 12, 1915. SerialpNo. 39,311.

, State 'of Kansas, respectively, have invented certain new and useful Improvements inl Tank-Cars, of which the following is a description, reference being had tothe accompanying drawings, which form a part of v our specification.

Our invention relates to tank cars .made of steel sections having their sides {ianged so as to extend substantially at right angles thereto, with the abutting-fianged sides of the various sections arrange'd 'to extend outwardly; the sections being preferably arranged to extend circumferentially, so that the adjacent flanges will provide 'circumferential ribs adapted to be secured together on the outside of the cara The object of our invention is to provide a tank car possessing the element of safety, of a degree lgreater than that obtainable with the constructions at present in` use;4 and, at the same time, a construction which will be inexpensive to manufacture. i

Our invention contemplates a construction wherein all the seams between the various sections or portions of which the car is constructed, .and which are subjected to strains, will be located on' the' outside of the car where they may be readily accessible for the purposes of repair and the like, thereby eliminating the difficulties and dangers at present encountered in making repairs to tank cars vas heretofore constructed.

Another'object of our invention is to prov ide a tank car construction provided with means .for preventing rolling or sidewise movement of the tank on its underframe;

` and, at the same time, provide means 'which will eifectually prevent, the tank from surging longitudinally on its underframe.

A further object lof our invention is to providel a tank car having means for supporting the running-boards'and the various heater-pipes; said means being so arranged that these elements will be entirely supported by the external rivet-seams of the shells or sections constituting the tank car.

Another obj ect of our invention is to provide an outlet or' drain' for the tank car of such construction that sealing of the valvedrain at the bottom of the tank car will be unnecessary, while, at the same time, the

drain or outlet will be of such construction'` that in case of its becoming broken in a Wreck' or derailment, the outlet-valve will not be opened thereby to allow the contents of the tank car to drain and become lost.

The invention possesses other advantages inherent in the construction, which will be apparent from the following de-` tailed description.

struction as well as the arrangement of the heater-pipes and longitudinal underframe anchor of the tank car. Fig. 2 isa partial end elevation and partial sectional view, the

sectional view being taken on 'the line A-A of Fig. l to more clearly show the method of supporting the heater-pipes or coils, and

I n the drawings: Figure l is aside ele-y kvation and partial longitudinal sectional view, illustrating the generaloutside con-t also the manner for securing the runningboard bracket or support. Fig. 3 is an enlarged longitudinal sectional view, taken through the central bottom portion of the tank int mediate of its ends to more clearly illustrate the application and construction of the long-itudinal frame-anchor, as well as the location and manner of application of the heater-pipes or coils and the tank-valve and drain. Fig. 4 -is a partial 'transverse sectional View, 'taken on the line B--B of Fig. 1, -to-wit through the longitudinal frame-anchor also shown'in Fig. 3. Fig. 5 is a detail view, partially in section and partially inelevation, illustrating one form of longitudinal joint and arrangement of a filling-strip between the transversely flanged ends of the shells or sections for the purpose of providing a metallic running-board.

Fig. 6 is an enlarged detail illustrating the.

method of providing transverse anchors for connectingthe tank to the `underfrarne of the car, so as to prevent sidewise rolling of the tank on the underframe; the anchor attaching member is shown in place between the ends of the stay-sheet member; a portion only of the stay-sheet member being shown, with the adjacent section of the tank removed. Fig. 7 is a side elevation and partial longitudinal sectional view illustrating a modified form of our improved tank car; showing, like in Fig. l,the general outside construction as well as the arrangement of ti'e heater pipes' and the longitudinalund' yrframe of the car. Fig. 8 4is an enlarged several sections, illustrating another modilied form of our invention; the ligure showing one end` and adjacent section, With the tank-head or end member secured in place. Fig. 9 is a vertical sectional view, taken on the line 9--9 ort Fig. 8, looking in the direction of the arrows'.

ln the particular -exemplification of our invention, as illustrated in the drawings, the tank car is composed of a series of4 metallic sections 10, the sides whereof are flanged and presented outwardly, as can more clearly be seen at 105L in Figs. 3 and l. The sections `are preferably formed of continuous sheets arranged transversely ot the tank car and bont into the cylindrical form or ring as shown, with the ends of the sheets or sections preferably secured together Aby imelding; the welded joint in such construction being preferably arranged at the top of the tank car so as to extend parallel with the longitudinal axis thereof, as shown at 1G't in Fig. E..

instead oil uniting tbeends of the various sections as just described, the ends may be flanged or bent outwardly, as shown at 1Gb in Fig. 5, so as to permit being riveted together, as shown at 11 in said ligure. lt is preferable to have the ends bent to such an extent as to permit at least a double row oi rivets as shown, which vrill provide a seam extending transversely of each section 10 adjacent the top oi the tank as shown in Fig. 5.

ille prefer to provide the seams just referred to with a filling-strip l2, see Fig. 5, the filling-strip 12 being made of a lengthL greater than the bent-up ends of the sections so as to provide an extended portion, which is bent at an angle to the seam-forming portion so as to entend horizontally and thereby provide a metal rmlning-board extending' lengthwise `of each section and therefore lengthwise of' the tank car, as more clearly shown to the right in Fig. 1. The outwardly extending portion oi this filling strip 12 is supported by means of brackets 13, each of which comprises a plate or member arranged intermediate ot the adjoining sides of the dilerent sections 10; the plates or brackets 13 are arranged to act as a portion of the filling strips between the transversely ei:- tending seains ol' the tank car. The remainder or main portion of the transverse seams are (provided with a filling strip 14: intermediate of the adjacent flanged sides of the respective sections, thereby materially strengthening the construction in a radial manuel', and, at the same time, providing a good,callzir:,1r 1strip for producing a fluidtight jbint. its very clearly shown in Fig. 2, the filling-strip 14 is cut away to receive the bracket-member 1S, which, of course, is made of a thickness equal to that of the filling strip 14. After the filling-strip 14: has been tiva/aaa inserted between the flanged sides of the respective sections, the flange-portions are secured together in any suitable manner, as, for example, by means of rivets indicated at 15, which pass entirely through the adjacent flanged portions and the lillinOf-strip and provide fluid-tight connections.

The filling-strips 14, Where they,4 extend about the lower part of the tank-fear, are preferably provided with inward extensions or portionsJ 14, as shown in Figs. 2 and 4, in order to provide a suitable bracket or support for the heater-coils 16 arranged Within the tank car along the bottom-portion thereof. The extended or bracket-portions 14 are preferably provided with suitable holes or sockets 17, see Fig. 4, arranged to receive the various portions or lines of the lichtercoil 1G. The inwardly extended pdrtions or brackets la are also provided with the eularged openings 1S, see Figs. 2 anda, arranged at points adjacent the walls of the tank car so as to aliord proper circulation for the fluid contained in the tank, and thus also permit the tank to be completely drained.

ln. order to prevent longitudinal Inovement or slipping ot' the tank on the underlrame, We provide a longitudinally disposed traute-anchor casting 19, see Figs. 3 and Ll, which is arranged to form a lower portion of the tank shell; the length oi' the anchorcastingltl being preferably commensurate with the 'ividth of one of the intermediate metallic sections 10 of the tank car, so that the ends ot the longitudinal anchor-casting 1f may be secured to the flanged sides 10a of the adjacent sections 10, as shown in Fig. fl. The connection between the anchor-casting 19 and the sections are preferably made by riveting the respective parts together with an intermediate lilling or calking strip 1l, as shown in Fig. 3.

The anchor-casting 19 also has the ends of the shortened or middle section 10 secured to it, see Fig. t; the anchor-casting 19 being provided with the flanged sides 19L to which the flanged or bent ends 10 of the section 10 are secured by means of suitable rivets, as shown in Fig. 4:. ln order to provide a fluidtight connection, We prefer to Weld the entire joint between the anchor-casting 19 and the sectional Wall of the tank car, preferably employing the autogenous method so as to produce the joint, as indicated at QOin Fig. 4.

IAside from acting as a frame-anchor, the casting 19 is also intended to. provide a suitable valve-seat 21l for the valve 22. Valve 22 is preferably provided with valve stem 22 which extends to the top ot' the tank-car, so that it may be operated through the manhole 23 shown in Fig. 1. The man-hole is provided with a suitable cover-plate 25 which may be sealed to the lcover or top 25 means ofI the bolts 28?.

' l This constructionand arrangement will preof the tank-dome 26 after the car has been Y filled. n Anchor-casting 19 is provided with the` downwardly presented walls 19b extending lengthwise thereof, -which are adapted to come intermediate of the center-sills 27,27, see Fig. 4Q The casting 19 is also provided with a discharge spout or port 19", arranged between the walls19b; the lower end of the port 19,beingfreinforced by the web-portion-19?, formed" integral with walls 19",

thereby also' reinforcing the side walls 19". The web-portion 19d provides a securing point .for the spout or extension 28 connected with the drain-port 19; the spout or extension'28 being secured to the web 19d by The j downwardly presented walls or flanges 19h of the anchorcastingare also provided at their bottoms with the inwardly-presented flanges 19e, to which cover-plate 29 may bel secured, by means of suitable bolts, as shown in Fig. 4. As is evident from the construction, the'inwardly presented webs or flanges, and the cover-plate, together withthe webs 19d, will reinforce the side walls 19", and therefore also the center-sills 27,27. The lower end of `spout or extension 28 is preferably shown threaded to receive al cap 30.

We prefer to provide the anchor-casting 19 with the horizontally disposed flangeslQ, adapted to rest on top of the center sills 27, see Fig. 4, .while thel downwardly presented walls 19b abut against the inner sides of the center-sills 27 2l. The construction of anchor-casting shown and described will prevent the center-sills buckling either upwardly or downwardly by 'reason of they;r

flange-portions 19t and the cover-plate 29. The anchor-casting 19 is also providedat its ends with the vertically disposed flangevportions 19g, .which are adapted `to abut against filler-blocks 31, 31, which 'are secured between the center-sills 27 27 and securely rivetedlthereto, as shown in Fig. 3.

vent longitudinal movement of the anchorcasting between the center-sills and therefore also of the tank.

The spout or extension 28 is preferably made` lighter in constructio-nthan the outlet port 19c formed in thepanchor-casting, so that, in case of wreck or derailment,

. should the lspout or extension 28 become broken, it will not necessarily break the ,port-portion 1,9c provided with the valve- Seat'and therefore may preventthe valvel becoming unseated; the construction being intended to avoid the possibility in case of accidents, of allowing vthe contents to drain ofi". The vanchor-casting 19 is also shown Vprovided with suitable flanged openings 19h,

v 19, see Fig. 3, adapted to receive the ends of the heater-coils 16; the flanged openings being also intended to receive the inlet and outlet pipes 32 and 33, respectively. Pipe 32 is intended to be connected with a suitable source of heat-supplying medium, while the pipe 33 will, in this instance, constitute the discharge or return pipe. As previously described, the heater-pipes are arranged along thel bottom of the tank-car, being seated in the slots 17 arranged in the extension 14a of the filler-strip arranged-at points intermediate ofthe ends of the tank-car;

the extensions 14a of the filler-strip, near' the ends of the tank car, being preferably provided with holes, instead of slots, as shown in Fig. 2, for the passagel of the heater-coils or--pipes 16,-so as to firmly hold the heater-coils against displacement, and

yet, at the same time, permit .the heater-k coils lto be easily assembled.` .if v

As more clearly shown in Fig. thfejcylindrical tank is supported by meansIof the body-bolster 34, which is preferably prol 38 which i's riveted or otherwise secured to the center-sills 27 and extends transversely of the underframe; the outer ends of the tie-rod 38 being preferably bent at a Suitable angle to permit of the passage therethrough of the anchor 37; the latter being firmly maintained in position by means of the nut39. The anchor 37 is pivotally secured to the clamp-member 40, which latter is shown riveted to the extended plate or member 41, which may either made integral with the filling or calking strip 14,

or be made separate therefrom, as shown in- Fig. 6. In order to permit of this construction and arrangement, the filling-strip 14 is shortened or cutaway sufficiently to permit the insertion of the plate or member 41, in a mannersimilar to the methodemployed where the'brackets 13 are inserted as previously described. It will be understood,

of course, that similar anchors are provided' on both sidesof the' tank, as showniin dotted lines in Fig.`2, and any desired number being employed; the anchors being arranged in alinement with the circumferential seamsor ribs of thev tank.

The juncture between the filling strip 14 and the plate ormember 41, as well as the juncture between the filling strip 14 and the brackets 13, may either be calked tight or welded in any suitable manner, preferably by the'autogenous method.

The method oi providing the side anchors, as described, provides a surface adapted to receive quite a nuinberof rivets, and, at the same time, permits sufficient flexing to accommodate any longitudinal expansion or contraction of the tank, due to the uneven temperatures to which the tank may be subjected, Without causing the circumferential seams to spring' or become alleeted.

A The ends of the tank car are provided with ladders -l, leading upward to the runningn boards 12 arranged along the upper sides of the tank, and the running-boards are also preferably provided with the hand-rails 13.

which extend lengthwise oft the car and may also be continued across the ends of the tank car, as shown in. Fig'. Q, so as to perlnit the brakeman or operator to cross troni one runningboard to the other with safety.

The donne 2G is provided with a suitable safety valve Llia "which may be set to the desired pressure for testing, in accordance with the governnxent regulations or rules. The concavoconvex or dshed ends 4.5, 115, are also provided with outwardly presented flanges, as shown at 4G, in Fig. l, so to permit the heads or ends l5 to be riveted or secured to the lianned sides ot the `adjacent shell-sections 10.

`With our improvedconstruction, all seams Will be arranged on the outside of the tank, Where they are accessible for ilninediate inspection and repair without the necessity et first having;` to empty the tank.

The importance of this construction is greater than ma): seein apparent, as many serions accidents and situations have been; encountered with tank cars heretofore constructed, while passim@` over a hed of hot cinders, due to leaky joints.

lith our iuuziroved construction, should a seam or joint become leaky While the car is in transit or filled, it is evident that the joint may be immediately repaired on the exterior ol. the tank without first being emptied, thereby obviating the dangers heretofore encountered.

As 1s apparent from the construction shown and described, the tank may be condstructed independent ot the car-traine and subsequently placed thereon and secured thereto by the longitudinal anclioncasting' 19 and the tieamclujirs 37; the longitudinal anchor 19 fitting' between the center-sills intei-mediate ol' the filling-blocks 31. The eover-plate 29 is then secured in place by means ot bolts, as shown in Figs. 3 and 4, so that the tank will be securely fastened to the frame oi the car. It is also evident therefore that the tank may he readily removed by simply releasingl the tie-anchors 37 and removing.' cover-plate 29.

In the modilied form of our invention, as illustrated in Fig. 7, the tank car is cornoosed of a series of metallic sections 10c, the

invaeaa sides whereof are flanged and presented outwardly in the saine manner as thesections of the `tank car illustrated in the first sii: ligeros of the drawings.

sections, which constitute the tank-portion of the cal', are each provided with circumterentially extending ribs or corrugations et? whereby the respective sections l0 will not only be strengthened in a transverseV shown at 10" in Fig. 5, so as to permit theV ends being riveted together in. the sanne man-` ner as in the previously described construction.

The circuinferentially disposed seams be4 tween adjacent sections are prete ablypro` vided with sealing strips as in the previ' ously described construction; and the running-board, which extends lengthwise oit the tank-car, may be formed in the saine Jnanner ns that previously described; or, if desired, the runninp,r board may be otherwise formed and secured in place.

As the frellcral arrangement and manner ot securing the heater coils or pipes is similar to that shown in the first figures of the drawings, a detailed description theremc will be unnecessary. The tank car shown in Fig. T, like the one shown in Fie'. l, is provided with a similar longitudinally disposed traine-n1e1nber castings,r or anchor 19 'secured in place in a similar manner and also providing a suitable valve-seat and down- 1ardly presented extension or spout for the discharge adapted to receive the extension or nozzle 28, shown in Figs. 3 and fl, all ol `which is to be intended to be arranged between the longitudinal center sills of the car. The anchor-casting, illustrated in Fig. 7, is intended to be identical with that show in Figs. l, 3 ande.

ln Figs. S and 9, We shoe a third modi lied torni of the invention in so far as the construction of the .respective sections of the tank car are concerned. In this modification, the sections 10d are formed ot' sheet metal provided withthe ribs or corrugations 48 extending transversely of the sheet so as to extend longitudinally of the tank car when the sheets have been bent into the cylindrical form or ring, as shown in Fig. 8. The corrugations extend substantially throughout the width of the sheet, `With the In the inodilied; form, illustrated in Figa 7, however, the

ends' of" the corrugations tapering or 'diminishing'- in depth, as can more clearly be seen to the left of Fig. 8, in order to permit the sides of the sheet or sections to be hanged, as shown at 49, formed so as to be presented outwardly in order that. the conl nections between *the various sections may be made on the outside of the tank car. The seam or joint between the respective sections lo is preferably provided with an intermediate sealing-strip 14a riveted lbetween the abutting flanged ends of adjacent sections. The ends of the tank car, as illustrated in Figs. 7 and 8, are closed by the end-members or 15 heads 45, made concavo-convex similar to the ends ofthe tank carshown' in Fig. l; the heads or ends having their peripheries flanged so as to extend outwardly in -a similar manner to the, flanged sides of the various sections. The longitudinally disposed ribs or corrugations 48 will naturally strengthen the respective sections both longitudinally and radially, at the same time permit .the necessary expansion' and" contraction of the tank resulting' from variations in temperature.

The tank car in other respects may be similar to'that previously described, with a portion of the calking or sealing strip 14a cut away at the proper point to receive the bracket-members 13C, see Fig. 9, to act as a support for the running boards Iarranged longitudinally of the tank car.

g With our improved constructions, repairs (fthe tank-proper may be easily made because of the fact that the various seams, formed by the above sections from which the tank is constructed, are located on the outside of the tank, and therefore accessible,

thus obviating the necessity of first scalding out thetank, as is the case with constructions as at present in use, with the result that' the expense of maintenance is materially lessened. At the Same time, con- 15 structions are provided possessing greater radial strength by reason of the circumferential ribs resulting from the employment of the flanged sections 'and the reinforcing filling or calking strips. The

strength' of the tank carmay be increased if desired by the employment of sections of less width, thereby p1 oviding a greater numy ber of cylindrical seamsdue to the employment of a greater number cylindrical sections necessary to provide a tank c ar of the desired size;A or by providing the corrugations oir-.ribs shownland"described. a

It is evident from the constructions shown and described that if any of the joints of the tank car sncild become leaky,`the seams or joints may be quickly repaired on the-cat exterior regardless of whether or not the tank is'illed or em tied, as all of the seams of joints areflocat'd on than. tank car exterior. The importance of such a construction will be readily apparent. Serious conditions have resulted in the use of the ordifnary type of tank car where leaks .have been sulted in a considerable loss of the oil because of the inability to make repairs while the car is lled with oil.

We have shown and described what we believe to be the best forms 'of our invention; certain details of construction, however, may be modified without departing from the spirit of the invention, and we do not wish to be understood, therefore, as limiting ourselves to 'the exact construction shown and described.
